FLUID-FUEL BURNER.

Original No. 1,542,142, dated June 16; 1925, Serial No. 750,279, filedNovember 17, 1924. Application for reissue filed July 12, 1927. serialNo. 205,246.

Mdy invention relates to improvements in. flui fuel burners of the typeused in domestic cooking stoves and the object of my invention is toprovide a fluid fuel burner that embodies means that will prevent theflooding of the interior or body portion of the burner and fire box ofthe stove with fluid fuel if such fuel is not in a gaseous state.

The fluid fuel burners now in common use are constructed in such amanner that when the fluid fuel is not gasified the fuel passes withinthe body portion of the burner and into the fire box Where it becomeslighted and burns causing the burner, fire box and flues to becomecoated with soot and also causing a great amount of smoke while in myburner all these objectionable features are eliminated by providing afluid fuel conduit within the burner body at a slight upward inclinewith respect to the horizontal which conduit is also provided on itsdischarge end with a well or shallow receptacle arranged to catch thefluid fuel and revent the same from being discharged into the burnerbody that angle at which the conduit being such that the fluid fuel willflow back into the ash it of the stove.

I accomplish these objects y devices illustrated in the accompanyingdrawings,

wherein- Figure 1 is a view in longitudinal section showing one form ofburner having fuel inlet means constructed in accordance with myinvention;

Fig. 2 is a view partly in plan and partly in horizontal section takenon line 2, 2 of Fig. 1; and

ig. 3 is a view in cross section on line 3, 3 of Fig. 1.

Referring to the drawings throughout which like reference numeralsindicate like parts, 5 designates a burner body which is erein shown tobe rectangular shape.

My invention consists in the provision within the burner body 5 of afuel inlet conduit 6 which enters the burner body on an upwardinclination with respect to the horizontal and which terminates in means7 forming a well 8 in which oil may collect and from which it will flowbackwardly along the conduit and out of the outer end thereof instead ofbeing discharged within the body of the burner.

The means 7 forming the well 8 that is illustrated in the drawings is inthe nature of a T-fitting connected with and extending crosswise of theconduit 6 in a horizontal position and open at both ends and is providedacross the lower segmental portion of both ends with webs or dams 9which cooperate in forming the well 8. It will be understood that thewell forming member 7- and alsothe conduit 6 may be integral with thebody portion of the burner if desired and may be Varied in shape to suitthe requirements of the burner body into which it is incorporated.

The outer end of the conduit 6 may terminate outside of the burner bodyin a suitable location, as in an open ca 10, where a plentiful supply ofair may obtained.

The burner is provided with a gasifying pipe 11 connected therewith inany suitable manner so that it passes through the area that is heated bythe flame when the same is in operation, the end or tip 11' of said pipebeing arranged to project into the cap 10 and being disposed inalignment with the fuel conduit 6 and forming a tip from which a jet offuel may be delivered into the conduit 6. The burner is also providedwith a plurality of circular outlets 12 disposed in the top and sideportions of the burner body in which outlets may be placed burner tipsof any well known make.

In the operation of my burner the fuel will be gasified in its travelthrough the pipe 11 and will issue from the tip 11 as a jet 90 of gaswhich will be directed across the gap in the cap 10 and into the conduitpipe 6 after the fashion common to Bunsen burners.

If for any reason the oil is turned on too quickly in priming the burneror the flame a5 is extinguished while the burner is in operation theliquid fuel instead of gas will be jetted into the pipe 6 and, unlessthe pipe 6 is provided with means for disposing of this liquid fuel, thesame will be ignited in 100 the burner body and burn with smoke and sootthat tends to clog up the burner tip.

If the fuel is turned on in my burner before the pipe 11 is heatedsufficiently to gasify the same, liquid fuel will be emitted from q thetip 11 into the well 8 and will flow rearwardly along the pipe 6 and outinto the ash pit of the stove or furnace in which the burner is disposedor into any receptacle that may be provided for catching the same 1 thusavoidingb the liquid fuel. in a non-genetics? state Wifilin the burnerbody.

The foregoing description and accompanying drawings clearly disclosewhat I now consider a preferred embodiment of my invention, but, it willbe understoodthat this disclosure is merely illustrative and thatsuehehaages inzthe construction of the burner may be resorted to as arewithin the-scope and spirit of the invention.

What I claim is;

. 1. In a fuel inlet means for an oil burner the combination with an oilburner body, of a fuel inlet conduit open at the outer end and arm d toextend into said burner body in upw y inclined relation to thehorimental, and a T-fitting forming a well at the inner end of saidconduit, said T-fitting having outlet openings located above the levelof the highest oint of-the bottom of said conduit where y liquid willnot be discharged fiom said outlet opening but will flow by gravityoutwardly 'throughsaid conduit.

2. In a fluid fuel burner, a'burner body, a fuelinlet'pipe extendinginto said body and. inclined upwardly relative to the horizontal the;outer end of said. inlet pipe being open, means for delivering a jet offuel into the outer endoi said inlet pipe, and a enclosing walls of saidwell extending laterally from saidinlet conduit and being-of such heightas to cause a return flow of un- ,gasified fluid, that may collecttherein, into said conduit and out to its point of delivery. In'witnesswhereof, I hereunto subscribe my name this 15th day of June, 1927.

PETER, JOHNSON.
